C REAM-SEPARATOR- SPECIFICATION forming part of LettersPatent N o. 712,390, dated October 28, 1902. Application filed April Z9, 1902. `Serialill'o. 105,129. (No model.)

T0 a/ZZ whom it may concernl Be it known that I, IVAR PETER BAGGER vKNUDSEIN, graduate of the Polytechnic, of` Kristiansgade 2, Copenhagen, Denmark, have uniform and to prevent thennskimmed milk s introduced from mixing with the cream that is separated Outland is directed inward toward the center, and thereby considerably to increase the working capacityof the centrifugal. i V

Figure 1 of the accompanying drawings is a vertical section of centrifugal apparatus according to this invention, andV Fig. 2 is a horizontal section thereof. 1

The unskimmed milkis introduced intoa centrifugal drum d` through a pipe b, which is concentric with the drum and in which there are provided parallel to its axis rows of holes c, through which theunskimmed milk runs into the drum and by means of which its distribution, in a vertical sense, is uniform. Each row of holes c has behind it in relation to the` rotation of the centrifugal a radial or almost radial dividing plateor wing d. Theunskimmed milk introduced runs outward in a thin sheet alongV the front surface of each of the plates d, Vbecause the milk owingfrom the interiorlmoves to places which have a continually-increasing rotating velocity, and it consequently has a tendency pressed against the front side of the dividing plate or wing d. At the same time the particles of cream or fat, which are separated at the periphery of the centrifugal and which besides traveling inward also attempt to make a movement forward in the direction of the rotation, impinge or bear against the rear surface of the dividingplate and follow it inward toward the center and take up chiefly the position Aindicated between the center,

`the dividing-plate, and the dotted lines in Fig. 2. By` the means described the mixing of the unskimmed milk with the cream separated threfrom is prevented in a very high f degree and the working capacity of the centrifugal is consequently greatly augmented. The device described can of course be used "also for centrifugals with liners of Aa knownl Where such liners divide the centrifdrum, the central vertical pipe therein, and

a series of vertical substantially radial plates extending from the said tube, the said pipe having a series of rows of apertures extending in a direction parallel with its axis, a row 'of said apertures being placed adjacent to theforward face of every one of said plates; `substantially as described.

`In'witness vrs/hereof I have hereunto setmy i hand inpresence of two witnesses.
